Endpoint Protection

Issue/Introduction

When Auto-Protect (AP) is enabled Intranet websites don't load or load very slowly using Symantec Endpoint Protection (SEP) and Bit 9 Parity Agent.

Behavior wasn't observed previously and Auto-Protect wouldn't impact the systems this way until after upgrading systems from Endpoint Protection 12.1 to Endpoint Protection 14.0.

No obvious errors, only behavior of the web pages not loading or loading very slowly. Trying to get a process dump of the main/parent IE process results in an Access Denied error instead of generating a dump file in the %temp% folder.

Cause

Interoperability issue between Bit9 Parity and Endpoint Protection 14.0.

Environment

  • Windows 7
  • Internet Explorer 11
  • Bit 9 Parity Agent
  • Symantec Endpoint Protection 14.0

Resolution

Create application exception and or whitelist our core process ccSvcHst.exe in Bit9 Parity.
